T 0 all whom it may concern:

Be it known that 1, WILLIAM FOWLER, a citizen of the United States, anda resident the county of Hamilton and State of Ohio, have invented acertain new and useful Machine for Trimming the Canvas of ReinforcedInsoles, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification.

In the manufacture of the greaterpart of welt shoes, insoles are used,which are rein- This canvas, after the insole is channeled and the lipsare turned up, is cemented and formed to the thus prepared leatherinsole. In the present state of the art, the overlapping part of the canvas is trimmed flush with the edge of the insole.

The product, thus obtained, is an insole with a ragged edge, whichdefaces the inside of the shoe. Furthermore the trimming .knifefrequently cuts the edge of the leather insoles and spoils them.

My invention has for its object to remedy these defects. 1 accomplishthis end by trimming with the hereinafter described machine theoverlapping canvas to a line edge of the leather insole, whereby I notonly avoid the cutting and spoiling of the leather insole but alsoproduce a clean edge of the same.

These objects I accomplish by that certain construction and arrangmeentof parts to be hereinafter more specifically pointed out and claimed,wherein I cut away the canvas, by slitting it against the surface of theinsole, by means of a properly placed lmife, and

feeding devices, which accomplish a cutting of the canvas withoutcutting the insole.

In the drawings, Figure 1 is a right side elevation of the machinepartly in section Fig. 2 1s a top plan view of the machine, on a,smaller scale. y

Fig. 3 is a front elevation thereof, on the same scale as Fig; 2.

Fig. 4: is an actual size detail side elevation of the trimming knifeand feeding disks.

Serial No. 2 5,374.

Fig. 7 is a like view showing the canvas trimmed away by my device. 1

The machine is mounted on a stand having a top 1, forward and rearstandards 2 and 3, and a basea. A shaft 5, having the idler and drivingpulleys 6 and 7 respectively, is ournaled in the rear standard, and iscaused to revolve by a belt 8. It has a worm 9 in mesh with a propergear 10 at right angles thereto which imparts rotation to the drivingshaft 11 of the machine. A rocker 12 is pivoted at 13 in the boss 14. onthe top of the stand, and journaled in this rocker is a.

shaft 15 that has mounted on it at its forward end the vertical feeddisk 16. At the rear end of the shaft 15 is mounted a pulley 17, whichis driven by a belt 18 that passes over a pulley 19 on the shaft 11.Thus when the shaft 11 is revolved the shaft 15 is also revolved, whichcauses rotation of the vertical feeding disk, and the rocker can bemoved by means which will be described below, without disconnecting theparts, because the belt will take an angular position without riding offof either pulley.

The shaft 11 is journaled in a standard 20 extending up from the base ofthe machine, and carries at its forward end a beveled pinion 21. Thispinion meshes with a like pinion 22on a vertical shaft 23, that extendsup through the top of the stand. On the top of the stand is formed ajournal 2 1 for this shaft, which slraft at its other end rests in thebase of the stand at 24:. Carried at the upper end of the shaft 23 isahorizontalfeeding disk 25, that is revolved by the said shaft. Therotation of theshaft 11 thus causes both a vertical and a horizontalfeeding member to rotate. The horizontal member has a smooth uppersurface preferably, and the edge of the vertical member is preferablytoothed so as to engage the insole when it is placed on the horizontalmember as will be described.

It can be seen that the relative position of the disk 16 and the disk 25may be changed by rocking the member 15. ,For this purfloor from themachine wher it is pivotally connected to a foot treadle 29. Adepression of the foot treadle will cause the inner end of the lever torise, and thus rock upwardly the member 15 raising the toothed feedingdisk away from the surface of the rocker 1 5, VA spring 31 connected tothe forward end of the locker and the boss 14" serves to hold therockeragainst this capstan. To adjust the position of the capstan, therocker is raised by "the foot-treadle and the capstan screwed in or outof the topyof the stand. I I I At the forward end of the rocker 15 ismounted the cutting knife which has a cut- I ting edge32, which isturned at an angle to the body portion 83 thereof. Slots 3 34:

' passes through the .are provided in the portion 33 of theknife, v

and screws 35, 35 are provided for securing the portion 33 to therocker. These screws passthrough the slots 3t, and it is evident thatthe position of the knife on the rocker and with relation to thetoothed'feeding disk 16 e accomplished by sliding these slots along the screwsto any "desired position.

On'apost 36 located-beneath the rocker is mounted the abutment holder37, which may be adjusted vertically ion 7 the post "by means offtheslot38inthe'holder and the securing screw 3 9, The abutment LO, which is tobe positioned so that its outer endwill lie, on the surface ofthedisk 25near its periphery, has a'slot 4e1"at'itsin1 '1er"end whichrides on atongue 42'form'ed on topof the holder '37. A large headed screw43 isprovided, "which 7 into the holder 37 ,thereby' providing an ad-'justjable mounting forthe abutment.

Theoperation of'the deviceis' as follows. An'insole 44 (Fig; 6). whichhas been covered with canvas" l'5,which said'canvas has been turned uparound the lip 46 of the insole,is placed on the revolving disk25 withthe edge of the insole against the abutment 4C0; Ifjneces'sary toproperly insert the insole .ui'iderneath the'disk 16, the diskmay beraised'by pressing on the'foot 'treadle. The insole is inserted underthe disk 16 with its edge" press ng against the abutment plate 40,andfthe revolving feeding disks then carry the insole underneath theknife edge 7 32. Thef'position of the abutment is so' adjustedthatthe'lip of the insole lying ad- Co'pies of t his patent may ts obtainedfor five cents each, by

7 enough to cut through th canvas covering" 45, but not to cut into theleatherof the insole. lVhen the operator guides the insole so that itsedge remains in constant contact with the abutment 40, the knife willcut through the canvas at 47, leaving a rim of leather clear around theinsole that is not covered by canvas.

Inasmuch as this cutting operation does not have to take place along theedge of the insole, there is not the probability of 'damaging the edgeof the insole or of tearing and raveling the canvas. A perfectly cleancut edge is formed on the canvas uniform throughout, the outer orsevered portion of the canvasremaining fast to the insole until it ispullel away by the operator.

"Having thus described my invention, what I claim as new'and desire tosecure by Letters Patent, is

1. In a device of the character described, the combination of an insolefeeding element, an abutment element to guide the edge of the insole,and 'a cutting element positioned with relation to the abutment so as toengage a canvas facing on the insole insideof the edge thereof, andpositioned'with relation to the feeding element so as to cutthe canvaswithout cutting the insole.

2. In a device of the character described, a revolving feed disk, arevolving feed disk disposed at right angles to the first disk, at fixedknife with its edge projecting below the second disk, and an abutmentpositioned over'the face of the first'disk and outside of the knife toserve as a guide for the edge of an insole.

3. In a device of the character described, a table, a contact memberover the table and adapted to rest on the surface of an insole, a cuttermember adapted to extend a distance beyond said contact member equal tothe thickness of the canvas on an insole, and a guide abutment adaptedto engage the edge of the insole outside of the position of the cuttingmember, for the purpose described.
